How to start MediaPlayer after it has been stopped in android

How to start MediaPlayer after it has been stopped in android - android

I am new to Android and in my app I am working with MediaPlayer.
When I first tap the start button, the song plays, but when I tap the stop button and then I tap on the start button again, the song does not start playing again. Here's what I have so far:
public class PlayngUrlFiles extends AppCompatActivity {
Button start, pause, stop;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playingurls_layout);
start = (Button) findViewById(R.id.button1);
pause = (Button) findViewById(R.id.button2);
stop = (Button) findViewById(R.id.button3);
final MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.start();
}
});
pause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.pause();
}
});
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.stop();
}
});
}
}

Try this :
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null) {
mp.stop();
mp.release();
}
}
});

just check like this way
if(mdpl.isPlaying()){
mdpl.pause();
} else {
mdpl.start();
}

You can not call start, it media player in on stop state. Take a look on the state diagram of media player MediaPlayer state diagram.
When you call stop, you have to call release(), and with start you get a new media player, or just call reset.

try this
public void onStopBtnClick(View view) {
if (mAudioHelper != null) {
mAudioHelper.stop();
displayMessage("Stopping!");
}
}

Here is code to set sound file.
if (mPlayer != null) {
mPlayer.stop();
mPlayer.release();
}
mPlayer = new MediaPlayer();
AppLog.d("Created new Media player");
try {
mPlayer.setDataSource(fileName);
} catch (IOException e) {
AppLog.e("Can't open " + fileName + " file", e);
}
Before playing u should call the mPlayer.prepareAsync() function.
if you want to pause/play you have to use this code:
if (mediaPlayer.isPlaying()){
mediaPlayer.pause();
} else {
mediaPlayer.start();
}
If you want to stop player use this:
if (mPlayer != null){
mPlayer.stop();
mPlayer.release();
}
mPlayer = null;
If you want to start song again use first functions and next with this steps

This code may help you..
#Override
protected void onDestroy() {
super.onDestroy();
destroyMediaPlayer();
}
private void destroyMediaPlayer() {
if (mediaPlayer != null) {
try {
mediaPlayer.release();
Log.d("here", "destroy");
} catch (Exception e) {
e.printStackTrace();
}
}
}

SOLUTION 1
for this solution, I took some info from here
public class PlayngUrlFiles extends AppCompatActivity {
Button start, pause, stop;
MediaPlayer mp;
/**
* remain false till media is not completed, inside OnCompletionListener make it true.
*/
private boolean initialStage = true;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playingurls_layout);
start = (Button) findViewById(R.id.button1);
pause = (Button) findViewById(R.id.button2);
stop = (Button) findViewById(R.id.button3);
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (initialStage) {
mp = new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
new Player()
.execute("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
} else {
if (mp && !mp.isPlaying())
mp.start();
}
}
});
pause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp && mp.isPlaying())
mp.pause();
}
});
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp) {
mp.stop();
mp.release();
mp = null;
initialStage = true;
}
}
});
}
/**
* preparing mediaplayer will take sometime to buffer the content so prepare it inside the background thread and starting it on UI thread.
* #author piyush

*/
class Player extends AsyncTask<String, Void, Boolean> {
private ProgressDialog progress;
#Override
protected Boolean doInBackground(String... params) {
// TODO Auto-generated method stub
Boolean prepared;
try {
mp.setDataSource(params[0]);
mp.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
initialStage = true;
mp.stop();
mp.reset();
}
});
mp.prepare();
prepared = true;
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
Log.d("IllegarArgument", e.getMessage());
prepared = false;
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
prepared = false;
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
prepared = false;
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
prepared = false;
e.printStackTrace();
}
return prepared;
}
#Override
protected void onPostExecute(Boolean result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
if (progress.isShowing()) {
progress.cancel();
}
Log.d("Prepared", "//" + result);
mp.start();
initialStage = false;
}
public Player() {
progress = new ProgressDialog(PlayngUrlFiles.this);
}
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
this.progress.setMessage("Buffering...");
this.progress.show();
}
}
}
SOLUTION 2
in order to avoid data downloding, try this
public class PlayngUrlFiles extends AppCompatActivity {
Button start, pause, stop;
boolean prepared;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playingurls_layout);
start = (Button) findViewById(R.id.button1);
pause = (Button) findViewById(R.id.button2);
stop = (Button) findViewById(R.id.button3);
final MediaPlayer mp = new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
prepared = false;
mp.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
prepared = true;
mp.start();
}
});
try {
mp.setDataSource("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
} catch (Exception e) {
e.printStackTrace();
}
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp) {
try {
if(!prepared) {
mp.prepareAsync();
prepared = true;
} else {
mp.start();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
});
pause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp) {
mp.pause();
}
}
});
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp) {
mp.stop();
prepared = false;
}
}
});
}
}

#MRodrigues was right about media player states. But instead of calling release() after stop, Modify your code as below.
Currently,
try {
mp.setDataSource("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.start();
}
});
modify to,
try {
mp.setDataSource("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
} catch (Exception e) {
e.printStackTrace();
}
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (!mp.isPlaying()) {
mp.prepare();
}
mp.start();
}
});

Android Media player run in background

I have created android app to stream online radio station and I want to run it in background using service.How to create service to run media player in background?

{
try
{

mPlayer.setDataSource(STREAM_URL);
mPlayer.prepareAsync();

Android is hanging when I press button to play music in second time

I used these codes from this reference. They want to click on button to play music and then click again to stop playing. (in their comment they said it was worked for them but hanging for me)
It is work just for first time. I mean for first click the music is playing. for second click the music is stop but for third click the phone emulator show this error:
unfortunately your program has stopped.
This is my code:
public MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.btnRain);
//mp = MediaPlayer.create(this, R.raw.rain);
mp = MediaPlayer.create(MainActivity.this, R.raw.rain);
btn.setOnClickListener(new View.OnClickListener() {
#Override
//MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.soundFileName);
// mp.start();
public void onClick(View v) {
if (mp.isPlaying()) {
mp.stop();
mp.release();
}
else {
mp.start();
}
}
});
}

In onCreate initialize mp as :
mp = new MediaPlayer();
The error is you are releasing the media player object mp, which destroys the object, call reset method instead of release.
if (mp.isPlaying())
{
mp.stop();
mp.reset();
}
else {
mp = MediaPlayer.create(LegalActivity.this, R.raw.free1);
mp.start();
}

use this below code for play and pause the music:
public MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.btnRain);
//mp = MediaPlayer.create(this, R.raw.rain);
mp = MediaPlayer.create(MainActivity.this, R.raw.rain);
btn.setOnClickListener(new View.OnClickListener() {
#Override
//MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.soundFileName);
// mp.start();
public void onClick(View v) {
if (mp.isPlaying()) {
mp.pause();
}
else {
mp.start();
}
}
});
}

Seekbar for mp3 from sd card

This code is to read a mp3 from raw folder,But I want to change my mp3 file to another file from sd card
its new code, music played but seekbar does not work properly, when i toch it seekbar come back to frist position
public class MainActivity extends Activity implements OnClickListener {
SeekBar seek_bar;
Button play_button, pause_button;
MediaPlayer mediaPlayer;
TextView text_shown;
Handler seekHandler = new Handler();

setContentView(R.layout.activity_main);

seekUpdation();
}
public void getInit() {
seek_bar = (SeekBar) findViewById(R.id.seek_bar);
play_button = (Button) findViewById(R.id.play_button);
pause_button = (Button) findViewById(R.id.pause_button);
text_shown = (TextView) findViewById(R.id.text_shown);
play_button.setOnClickListener(this);
pause_button.setOnClickListener(this);
String filePath = Environment.getExternalStorageDirectory() + "/Android/music.mp3";
mediaPlayer = new MediaPlayer();
try {
mediaPlayer.setDataSource(filePath);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block

// TODO Auto-generated catch block

// TODO Auto-generated catch block

}
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
}
});
mediaPlayer.prepareAsync();
seek_bar.setMax(mediaPlayer.getDuration());
}
Runnable run = new Runnable() {
#Override
public void run() {
seekUpdation();
}
};
public void seekUpdation() {
seek_bar.setProgress(mediaPlayer.getCurrentPosition());
seekHandler.postDelayed(run, 1000);
seek_bar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar seek_bar) {
// TODO Auto-generated method stub
}
#Override
public void onStartTrackingTouch(SeekBar seek_bar) {
// TODO Auto-generated method stub
}
#Override
public void onProgressChanged(SeekBar seek_bar, int progress, boolean fromUser) {
if(fromUser){
mediaPlayer.seekTo(progress);
seek_bar.setProgress(progress);
}
}
});
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.play_button:
text_shown.setText("Playing...");
mediaPlayer.start();
break;
case R.id.pause_button:
mediaPlayer.pause();
text_shown.setText("Paused...");

if(fromUser){
mediaPlayer.seekTo(progress);
seekBar.setProgress(progress);
}
}
#Override
public void onBackPressed() {
mediaPlayer.stop();
finish();
}
}

Just move this line
seek_bar.setMax(mediaPlayer.getDuration());
to seekUpdation() after
seekHandler.postDelayed(run, 1000);

Replace
mediaPlayer = MediaPlayer.create(this, R.raw.my_file);
with:
String filePath = Environment.getExternalStorageDirectory() + "/randomDirectory/yourFile.mp3";
mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource(filePath);
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mediaPlayer.start();
}
});
mediaPlayer.prepareAsync();

Want MediaPlayer to continue running when screen is locked

How could I make it so that my MediaPlayer continues to play even when the phone is locked and the screen is off, thinking it may have to do something of making it a service but not sure. If so how could I go about changing it to a service or is there a quicker easier fix?
Any help would be great!
Here is code:

Follow my tutorial below...In following tutorial i have stored .mp3 file in raw folder. if you have stored it in sd card and dynamically fetching that file then put its path in bundle and send it through intent which you can get in onStartCommand() method of your service.
MainActivity.java
public class MainActivity extends Activity implements OnClickListener {
Button startPlaybackButton, stopPlaybackButton;
Intent playbackServiceIntent;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startPlaybackButton = (Button) this.findViewById(R.id.StartPlaybackButton);
stopPlaybackButton = (Button) this.findViewById(R.id.StopPlaybackButton);
startPlaybackButton.setOnClickListener(this);
stopPlaybackButton.setOnClickListener(this);
playbackServiceIntent = new Intent(this, BackgroundAudioService.class);
}
public void onClick(View v) {
if (v == startPlaybackButton) {
startService(playbackServiceIntent);
finish();
} else if (v == stopPlaybackButton) {
stopService(playbackServiceIntent);
finish();
}
}
}
BackgroundAudioService.java
public class BackgroundAudioService extends Service implements OnCompletionListener {
MediaPlayer mediaPlayer;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
mediaPlayer = MediaPlayer.create(this, R.raw.abc);// YOUR FILE NAME
mediaPlayer.setOnCompletionListener(this);
Log.v("TEST", "1");
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (!mediaPlayer.isPlaying()) {
Log.v("TEST", "2");
mediaPlayer.start();
}
return START_STICKY;
}
public void onDestroy() {
if (mediaPlayer.isPlaying()) {
mediaPlayer.stop();
}
mediaPlayer.release();
}
public void onCompletion(MediaPlayer _mediaPlayer) {

Issues with replaying music in Android Media Player

To start off, playing and stopping music works fine. I've already searched SX, and have tried some of the solutions listed for this issue, but they haven't resolved my issue.
I have a "Replay Music" button, that is supposed to restart an .mp3 file from the beginning. I've got the necessary code in place (like reset(), prepare(), etc, in order for the media player to replay the music, but when the button is pushed, nothing happens.
I have all the OnClickListeners and other necessary things setup, it is just this one issue.
Below is the complete code for my "Replay Music" method. Any help will be gratefully received.
Just a thought: Perhaps it is something to do with the placement of the mediaPlayer.start() method call?
public void replaySoundButtonListener() {
Button testButton = (Button) findViewById(R.id.replayMusicButton);
testButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
mediaPlayer.reset();
try {
mediaPlayer.setDataSource("sdcard/InsomniMusic/insomnimix.mp3");
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
mediaPlayer.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mediaPlayer.start();
}
});
}

You only need to prepare and set the data source of a mediaplayer once. When you call reset the mediaplayer has to be reinitialised completely (set datasource again and call prepare). If you would like to reset the mediaplayer to the start of the song I guess you could use
mediaPlayer.setOnSeekCompleteListener(new MediaPlayer.OnSeekCompleteListener() {
#Override
public void onSeekComplete(MediaPlayer mediaPlayer) {
mediaPlayer.start();
}
});
If the song has already ended (or stopped otherwise), only mediaPlayer.start() will suffice (but I guess in your case you can never be sure of that).
More information on the start function here

I made a functions to start() stop() reset() and pause() in another Class
import android.content.Context;
import android.media.MediaPlayer;
public class AudioPlayer extends MediaPlayer {
private MediaPlayer mPlayer;
public void stop()
{
if(mPlayer!=null)
{
mPlayer.release();
mPlayer=null;
}
}
public void pause()
{
if(mPlayer.isPlaying()) {
mPlayer.pause();
}
else
{
mPlayer.start();
}
}
public void reset(Context c)
{
stop();
mPlayer=MediaPlayer.create(c, R.raw.one_small_step); //uzimamo .create(context,..) jer uzimamo iz res/raw lokalne datoteke
mPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
stop();
}
});
mPlayer.start();
}
public void play(Context c)
{
stop();
mPlayer=MediaPlayer.create(c, R.raw.one_small_step);
mPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
stop();
}
});
mPlayer.start();
}
}
//Here is my fragment
private Button mPlayButton;
private Button mStopButton;
private Button mPauseButton;
private Button mResetButton;
private AudioPlayer mPlayer=new AudioPlayer();
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v=getActivity().getLayoutInflater().inflate(R.layout.fragment_hello_moon, container);
mPlayButton=(Button)v.findViewById(R.id.hellomoon_playButton);
mPlayButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mPlayer.play(getActivity());
}
});
mStopButton=(Button)v.findViewById(R.id.hellomoon_stopButton);
mStopButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mPlayer.stop();
}
});
mPauseButton=(Button)v.findViewById(R.id.hellomoon_pauseButton);
mPauseButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mPlayer.pause();
}
});
mResetButton=(Button)v.findViewById(R.id.hellomoon_resetButton);
mResetButton.setOnClickListener(new OnClickListener(
) {
#Override
public void onClick(View v) {
mPlayer.reset(getActivity());
}
});
return v;
}
#Override
public void onDestroy() {
super.onDestroy();
mPlayer.stop(); //Nakon sto je fragment unisten MediaPlayer nastavlja radit jer je na drugacijem Threadu pa treba pozvati Stop();
}

How to start MediaPlayer after it has been stopped in android - android

Try this : stop.setOnClickListener(new View.OnClickListener() { #Override public void onClick(View v) { if (mp != null) { mp.stop(); mp.release(); } } });

just check like this way if(mdpl.isPlaying()){ mdpl.pause(); } else { mdpl.start(); }

You can not call start, it media player in on stop state. Take a look on the state diagram of media player MediaPlayer state diagram. When you call stop, you have to call release(), and with start you get a new media player, or just call reset.

try this public void onStopBtnClick(View view) { if (mAudioHelper != null) { mAudioHelper.stop(); displayMessage("Stopping!"); } }

This code may help you.. #Override protected void onDestroy() { super.onDestroy(); destroyMediaPlayer(); } private void destroyMediaPlayer() { if (mediaPlayer != null) { try { mediaPlayer.release(); Log.d("here", "destroy"); } catch (Exception e) { e.printStackTrace(); } } }
